Claims.

The present invention relates to apparatus for permanent waving and moreparticularly to a novel and improved heater for permanent wavmg.

5 Objects and advantages of the invention will be set forth in parthereinafter and in part Will be obvious herefrom, or may be learned bypractice with the invention, the same being realized and attained bymeans of the instrumentalities and combinations pointed out in theappended claims.

The invention consists in the novel parts, construction, arrangements,combinations and improvernents herein shown and described.

The accompanying drawing, referred to herein and constituting a parthereof, illustrates one embodiment of the invention, and together withthe description, serves to explain the principles of the invention.

Of the drawing:

Figure 1 is a fragmentary side elevation of one embodiment of thepresent invention and showing different types of heaters which may beused therewith;

Figure 2 is a detailed side elevation of a heater unit in accordancewith the present invention; and

Figure 3 is a longitudinal section of a cord gripping and supportingdevice in accordance with the present invention.

The present invention has for its object the provision of a new andimproved heater mechanism for permanent waving in which the heatingunits may be readily and individually removed, and replaced in whole orin part by other heating units of the same or a different kind. Afurther object is the provision of an improved heating unit which isbodily removable from a supporting member usually positioned above thecustomers head. Still another object is the provision of an improvedgripping and supporting member for the heater cords which may be bodilyremoved from or attached to a main supporting member, and which permitsthe length of cord between the supporting member and the customers headto be varied.

Referring now in detail to the illustrative embodiment of the inventionas shown in the accompanying drawing, a supporting and electricity 5Odistributing member is provided which is generally positionedimmediately above the customers head and is supported upon a standard10, or may depend from the ceiling. This supporting and electricitydistributing member, as

- embodied, comprises an annular member or drum 11 provided with aplurality of pairs of female connectors 12 set in the drum 11 in a pairof rows, one superposed above the other, and preferably with a row ofgrounding contacts 13 positioned between the connectors 12. Drum 11 is60, rigidly secured to the standard 10 in any desired manner.

Surrounding the annular member 11, and preferably positioned veryslightly above it, is a relatively large and narrow circular band 14,also 65, supported from standard 10 by means of radial spokes (notshown). Band 14 is provided with a plurality of slots 15 for receivingand holding the cord gripping and supporting members, later to bedescribed, and the number of such slots m 15 is preferably at least asgreat as the maximum number of heaters to be employed at any one time. I

The heating units in accordance with the present invention are bodilydetachable from 15. their support as a unit and comprise heaters 16,which may be of any desired type, as are used in giving a fiat wave, andas shown in Figure 2, or those of tubular form, as at 17 to be used inwaving a helically wound tress- As embodied, a pair of such heaters areconnected in series with the terminals 18 of the male portion of aseparable connector 19 by means of flexible conductors 20, the terminals18 being adapted to contact with a pair of terminals 12 on the annularmember 11.

The heating units preferably include means for frictionally gripping andsupporting the heaters 16 or 17 and their flexible conductors 20 uponthe circular ring 14, and for this purpose each of the conductors isprovided with a cord gripping device which is bodily detachable from thering 14. As embodied, this cord gripping device comprises a relativelysmall body 22, preferably of insulating material, and formed with a pairof spaced apart axially alined apertures 23 through which the heatercord 20 may be threaded. Positioned between said apertures 23, andcapable of axial alinement therewith, is an annulus 24 surrounding theheater cord 20, 1.00 and provided with a relatively smooth inner face.

Means are provided for resiliently urging annulus 24 out of alinementwith apertures 23, and into the position shown by Figure 3, so that itwill firmly grip and securely hold the heater cord 20 at any point,while permitting the relatively easy movement of the cord back and forththrough the device. For this purpose, a pin 25 is attached to annulus 24and extends radially therefrom, and is received within a socket in pin26 which is securely fastened in the body 22. A small spring 27 iscompressed between the end of pin 25 and the bottom of the socket in pin26, and serves to urge annulus 24 into frictional and gripping contactwith the cord 20.

For attaching the cord gripping device to the supporting ring 14, pin 26is provided with a narrow T-head 28 at its outer end, which correspondsin size and shape to the slots 15, and forms a bayonet connectiontherewith.

supported on the supporting ring 14, but may be readily removedtherefrom by rotating the gripping device degrees-and pulling it awayfrom the ring. I

. In operation, the required number of heaters are connected to theelectricity distributing member 11 by means of separable connectors 19,and the cord gripping and supporting members 22 are properly positionedand supported on the ring 14, with the heaters hanging downwardlytherefrom. After the heaters 16 or 1'? have been properly positioned onthe customers head, the slack in the heater cord 20 between thecustomers head and the cord gripping and supporting members 22 may betaken up by pulling the cord 20 upwardly through the cord grippingdevices 22, thereby relieving the weight of the heaters from thecustomers head and supporting them from the ring 14.

In case a particular heater becomes damaged, or it is otherwisedesirable to replace it, it is only necessary to remove the separableconnector 19 from the distributing member 11 and thereafter todetach'the two supporting and gripping devices 22, thereby freeing theparticular heating unit and permitting its bodily removal. In thesameway it is possible to remove all of the heaters and to replace themby heaters of a different type when it is desired to give'a' differentkind of a permanent wave. An operator need be provided with only asingle machine and different sets of heaters in order to give difierentkinds of waves, thereby reducing the cost of the equipment and effectinga great economy in the space required for the apparatus. The presentinvention also permits replacement of adefective heater instantly andwithout the use of any special tools or equipment.

The invention in its broader aspects is not limited to the specificmechanisms shown and described but departures may be made therefrom Theheads 28 may be passed through the slots 15, and by turning the grippingdevice 90 degrees to the. position shown in Figure 1, the heater cordsare within the scope of the accompanying claims without departing fromthe principles of the invention and without sacrificing its chiefadvantages.

What I claim is:-

1. A device for supporting a permanent waving heater cord comprising amember provided with a pair of spaced apart axially alined aperturesthrough which the heater cord may slide, an annular member to surroundsaid cord and positioned between said apertures, a pin extendingradially from said annular member and slidable in said first member,spring means for moving said annular member out of alinement with saidapertures to frictionally grip said cord, and a supporting pin extendingfrom said first member by which the, device may be supported.

-2. A device for supporting a permanent waving heater cord comprising amember provided with a pair of spaced apart, axially alined aperturesthrough which'the cord may slide, a second apertured member to bepositioned in alinement with and between said axially alined apertures,means for resiliently urging said second member out of alinement, and apin by which said device may be supported.

3. In a permanent waving machine, the combination of supporting andelectricity distributing members to be positioned over the customers arehead, a set of heater units for permanent waving, each heater unitcomprising a detachable connector for attaching a pair of heaters tosaid member, flexible conductorsand a pair of heaters and individualsupports through which said conductors may slide and by which'said con-'ductorsare frictionally held, and means for inconductors.

5. A heater unit for permanent waving including in combination a pair ofheaters, a separable connector, flexible conductors connecting saidheaters to said connector and individual gripping devices for supportingsaid conductors, slidable with respect to said conductors and grippingtheir respective conductors in any position.
